Order 5. COLEOPTERA. 527 



The Hoplides have the mandibles small, depressed, and apparently divided longitudinally into two 

 parts ; the inner membranous and the outer horny. The extremity is not sensibly toothed ; the 

 labrum is scarcely visible ; the maxilla; have rarely only minute teeth ; the two hind tarsi have gene- 

 rally only one claw. 



Dicrania, Lepel. & Serv., have two ungues, alike, and bifid in all the tarsi ; body polished ; species inhabiting 

 Brazil. 



HopUa, Ulig., has but a single unguis to the l)ind tarsi ; those of the other feet are unequal and bifid ; the hind 

 tibiae are terminated by a coronet of minute spines; the body squamose. {Uoplia argentea,0\b!. H.pulveru- 

 tenia is the only British species.] 



Monocheles, lilig., differs from Hoplia in the clypeus being inform of a triangle, truncated in front; thighs ol 

 hind legs very robust ; tibiae short, with a strong curved spur. 



The fifth section, Anthobii, is composed of species closely allied to the Hoplides, but having the two 

 divisions of the lower lip produced considerably beyond the mentum, and the elytra gaping at the tips, 

 which are rounded ; the antennse have nine or tea joints ; the last three compose the club ; the ter- 

 minal lobe of the maxillae is membranous, silky, and pencil-like, but leathery in others ; the upper lip 

 and mandibles are more or less solid as they are more or less exposed. These insects live upoa 

 flowers or leaves. [None of these insects are found in England ; they chiefly inhabit the southern 

 parts of Europe and the warm parts of both hemispheres.] 



Some have the labrum and mandibles exserted, and two equal and entire claws in all the tarsi. 



Glaphyrus, Latr. (having the inner edge of the mandibles toothed, the club of the antennae ovoid, and the hind 

 legs large), and 



AmpMcoma, Latr. (having the mandibles without teeth on the inner edge, and the club of the antennae globular, 

 and all the legs of ordinary size), have the basal joint of the club of the antennae concave, and inclosing the others. 



Anthipna, Esch., has the club of the antennas composed of five leaflets. 



The others have the labrum and mandibles covered or not exserted, and some at least of the ungues of. the tarsi 

 are bifid, and in some of these all the tarsi have two ungues. 



Chasmatopterus, Dej. (having all the tarsal ungues bifid), and 



Chasme, Lepel. & Serv. (having the larger unguis alone of the two posterior tarsi bifid), have the hind legs 

 scarcely differing from the others, whilst in 



Dicheles, Lepel. & Serv., the hind feet, at least in the males, have the thighs very thick and toothed ; the tibiae 

 thick, and terminated by a strong claw. 



Those which have but one unguis in the two posterior tarsi are LepitrLv, Lepel. and Serv., having nine joints m 

 the antenna;, and the terminal lobe of the maxilla; very smaW—Pachycnemus, Lepel. & Serv. (with 10-jointed 

 antennee, the maxillary lobe long and narrow, and the elytra narrowed behind), and Anisonyx, Latr., having the 

 elytra oblong, rounded behind, with the hind tibiae subcylindric or elongate-conic. 



The sixth and last section of the Scarahffiides {Melitophili) is composed of insects having the body 

 depressed, often of an oval form, brilliant, without horns, the thorax trapeziform or nearly orbicular ; 

 an axillary piece occupies in the majority the space between the posterior angles of the thorax and 

 the shoulders of the elytra ; the anus is not covered ; the sternum is often prolonged into a point or 

 advanced horn ; the claws of the tarsi are equal and simple ; the antennae have ten joints, the last 

 three of which form the club, always leafed. The labrum and mandibles are concealed, and in the 

 form of flattened plates, entirely or partly membranous ; the maxillae are terminated by a haiiy lobe 

 like a brush, without horny teeth ; the mentum is ordinarily ovoid, truncated above or nearly square, 

 with the middle of the upper edge more or less concave. The larvae live in old rotten wood : the 

 perfect insect is found upon flowers, as well as on the trunks of trees, in places where the sap 

 exudes, and which they greedily lap up. 



This section is divisible into three principal divisions, which correspond to the genera Trichius, 

 Fabr. ; Goliathus, Lamarck ; and Cetonia, Fabr., in its restricted state. The Melitophili of the two first 

 divisions have not the sternum much porrected, and the lateral or axillary piece of the mesosternura 

 {Epimera, Aud.) is not generally exposed above. Another character, which appears still more rigorous, 

 consists in the labial palpi being inserted in lateral cavities on the anterior face of the mentum, th 

 sides of the mentum extending behind them, and thus guarding them, 



The Trichides have the mentum either nearly isometrical, or longer than broad, with the maxilla 

 exposed. This division comprises the single subgenus 



Trichius, Fabr. [which has been cut up by Kirby, Gory, and others, into various minor subgenera]. TrlcMu 

 Mobilis, Linn., and T. fasciatus, Linn, [are British species; the latter exceedingly rare]. The female of T. hemi 

 pterus, Linn., and some others from North America, are distinguished by having a long and slender horny instiu
